Energy Excelerator launched in January 2013 with a mission to help startups solve the world’s energy challenges. That mission is now well underway with a third cohort of companies working its way through the Hawaii-based incubator’s program.

Over the past three years, Energy Excelerator, or EEx, has mobilized $15 million in funding to support 42 different companies that have gone on to raise another $227 million in follow-on funding. Over the next 18 months, these companies plan to raise more than $240 million in new investment.
